By body type I meant ecto, meso, or endo? I'll assume ecto.

Calories - 2631
With an ectomorph body type at a body weight of 165 pounds and a "Moderately Active" activity level, your total daily caloric intake should be 2631 calories.
Protein: 328.88 grams
Of these 2631 calories 1315.5 should come strictly from protein. That equals 328.88 grams of protein per day.
Carbohydrates: 243.37 grams
The calories derived strictly from carbohydrates each day should total 973.47 calories. This means your total carbohydrate intake per day in grams should be 243.37.
Fat: 38 grams
Fat intake should always be kept to a minimum. Out of the 2631 calories you consume a day only 342.03 or less should come from fat. That's a total of 38 or less grams of fat per day.
Pretty decent guide, helped me out quiet alot when I first started.
My diet?
Monday to Friday
pre workout:
5am - three penguin mints (caffeinated)
5.30am - whey protein, glutamine, creatine 600ml or more of water
post workout:
7am - whey protein, glutamine, creatine in 600ml of orange juice (anything with glucose)
7.15am - 1 cup of white rice, 250 grams of tuna, slice of grapefruit
3hr window:
9.30am - 2 scoops (1 serving) of nytro pro 40 (meal replacement)
12pm - 250 grams of chicken breast, 2 cups of green beans, 1 cup of brown rice, slice of grapefruit
2pm - 250 grams of chicken beast, 300 grams of brocolli, 1 cup of brown rice, slice of grapefruit
5pm - 125 grams of chicken breast, 2 cups of green beans, 1 cup of kidney beans, slice of grapefruit
7pm - 125 grams of chicken breast, 2 cups of green beans, 250 grams of spinach, 1 tablespoon of flax seed oil, slice of grapefruit
post cardio:
9pm - 250 grams of tuna, 2 cups of green beans, 0.5 cups of cottage cheese, slice of grapefruit
10pm - whey protein, glutamine, creatine in 600ml of skim milk
during the day i would on average drink 2 cups of coffee sweetened with splenda, and close to 11 liters of water
Equaling ~ close to 4050 calories, 520g of protein, 360g of carbs, 50 of fat.
Saturday:
Focus is to continue to eat properly and eat every 2-3 hours consuming quality protein
Sunday:
"Cheat" day, still eat properly, eat oats, different meats/vegetables, low cal jelly.
To get the best results I suggest training at the same time every day, preferably in the morning as it allows you to replenish your body throughout the whole day. I drink coffee because I like it, however it has also been shown to speed up your metabolism.
Anyway to summarize it very simply, lift heavy with alot of intensity and focus, get the fuck out of the gym in an hour each workout. Eat properly and enough to gain lean muscle, if you require supplementation then supplement and make sure you recover well (sleep).
